Made for extreme cold and high altitude conditions; the Alpha SV Mitten from Arc'Teryx features multiple components that are designed to work together to maximize warmth. These mittens are highly durable for operating ascenders on fixed lines and rappelling in cold, frozen conditions. A windproof outer shell can be used on its own or as an insulated over mitt for the Alpha SL or FL gloves. The removable Primaloft liner glove offers grip control and works with the outer shell to offer unmatched dexterity in any application. The Alpha SV uses waterproof/breathable GORE-TEX in the palm and a GORE WINDSTOPPER gauntlet to ensure no moisture or air seeps in, allowing for maximum heat retention. These mitts also feature removable wrist leashes and a carabiner clip in point to secure the gauntlet, reducing the risk of losing your mitts at high altitude where warmth is necessary.
